Be it known that I, DAVID L. .STUIJL,'3. citizen of the United States ofAmerica, residing at Birmingham, in the countyfof Jefferson and State of Alabama, have invented certain new and useful Improvements in Cone-Baking Machines, of which the following is a specificationf My invention relates to an apparatus for the manufacture of ice-cream cones and'likebaked pastries, and is more particularly adapted for hand operation. 1

My invention ismore particularly adapted for the production of cake cones @or like baked pastries in which the amount of sugar is sufficient to cause the baked product to stick in the molds and therefore makes neccessary the use of a sectional; separable mold to make easyand practical the removal. of the baked product. i l I One object of my invention is to simplify and perfect the mechanism for quickly separating andpositively reassemblingthe sections of the mold and for accomplishing this operation preferably by a foot pedal so as to leave the hands of the operator free.

A "further objectv of my invention is to simplifyand perfect the mechanism for the distribution of batter. i I i i H A further object of my invention is to improve the arrangement for heatingthe molds both above and below to produce a uniform cookingof the product. i i W My invention further comprises thenovel detailsof construction and arrangements of parts. which intheir preferred embodiment only are illustrated in the accompanying drawings, in which:

Similar reference numerals refer to simi- "lar parts throughout the drawings.

I have shown my inventionembodied in Fig.8 with a'rectangular frame having legs 1 which are provided with angles 2' for attachment to the floor. The frame comprises verticalend walls 3 connected to a back wall 4: and a "front wall Both the front and back walls are provided with downwardly extending central members 6 and 7, respectively, the. member 7 having attached at its base abearing bracket 8 in the outer 'end of which a pedal lever 9 is pivoted and adapted to: project forwardly through slots=1O and 11 in the extension members 6 and 'Z,"respec tively, this latterslot being enlarged at its base so as to provide an offset stop shoulder 12 which will engage and holdythe'treadle in lowered position, A link 13 is Jpivotally" connected to the treadle at its lower end and at its upper end is bifurcated and provided with pin 14; which works in the curved elongatedslots 15 atthe inner ends of the rocking levers 16, which levers are fulcrumed on, pins 17 seated in frontand rear walls of the frame and extending crosswise'thereof. At their free outer endstheseirocking levers are pivotally connected to vertical arms 18 which enter-slots 19 "at each end of the center member 20 of the mold and are pivotally connected theretoby pins 2i,- the slots being of such size and shape as to permit the arms to swingfreely'as they are moved by levers 16 to raise 'and lower the female mold; As illustrated, this mold comprises the central member 20 which preferably is cast inlong'itudinal sections which are riveted together.

vertical side faces is provided withhalf mold cavities for themolds .22. In'the' machineillustrated the central member is'provided on each side with nineofthese half molds. but of course' this number may be r This member extends v a from side to sideof the machine and in its to complete the molds 22. The central member 20 is trapezoidal in cross section with a recess along-its'base to lightenit.

This battertankis provided at its bottom with a .batter disch-arge pipe 58, see Fig. 7, which delivers .thebatter to the nozzles 59- which have a small batter-discharge passage therethrough. 'The rbatterinozz'les are. surrounded at their bottom endswith rubber packing :ringsror washers 60 which bearupon -a flat batter valve 61 pivotally mountedby means :of ascrew :pinon a web62von the pipe 58 midway between the :nozzles. :The batter valvezh-as batteri'ports 63 disposed in position to be moved by aihandl'e 64 :into register with the :nozzles 59.

E-achlatch bolt 66 is'operated by a suitable vclamp mechanism to .press the mold elements together'as showny-eac'h bolt ataits lower end issconnected to'and movable with -awlug'69 onz'an eccentricstrap or plate 70 which surrounds and is mounted upon 'an "eccentric Z71 efulcrumed ?to the, machine 1 frame by means of a pin 72 and provided with an operating handle 73. The eccentric 71 has its outervportion "enlarged to overhang the strap .orplate -70-andit thus serves to 'hold the "plate in operating position on the frame. The opening'in each lug 69 for the :latchaboltzis of such character as to permit the bolt to have the necessary angular play towards rand from the "machine to permit it'to be disengaged *by hand'ifrom the lugs 68 or to be swung inwardly to engage said lugs. "This l'oose' mounting may be accomilhe carrier 32, in alignment product.

plished by an enlarged bolthole :69 provided in the lug 69 forthe reduced threaded shank 66 of the bolt. The shoulder left on the bolt by this reduced shank serves to support the bolt on the lug 69. The handles are disposed in opposite directions at each side of the machine. When the latches are in operative position by depressing the handles Z3 a very great leverage is brought to bear through the eccentrics'and eccentric straps to pullthe bolts downwardly and with" great power clamp together the mold elements in their assembled position.

'To :Eacilit'ate'theopening of the molds afterfthe' cooking operation, Iprovide a lever 74 having an eccentric head 75 pivotally mounted in bearings 76 on the outer moldmemberQi, the eccentric being sodesigned that asthe lever is drawn upwardly the eccentric will "engage a lug 77 on the carrier for the cores and prize the latter upwardly to loosen it so that as soon as the latches are released it is free to be lifted by means of theliandles 78, The operator may be relieved otthis duty of raisingand holding the carrier 32 in its open position by the pro ision ot'counterweight mechathepedal is raised to close molds 22, the

operator then. shifts the batter tank above the molds and moves it lengthwise above them setting the valve 61 to discharge the batter at the desired rate. After depositing the batter, the handles 78 are grasped and the top carrier 32 drawn downwardly until its keeper lugs 68 engage under the catch nuts 67 of the latches and the cores assume position in the molds. i The operator then depresses the levers 73, causing the latch bolts 66 to clamp the carrier with great power against the molds and to hold theparts in this position during the cooking operation. the molds being heated above and below by the burners to uniformly cook the As soon as this has occurred the levers 73 are raised. the latches released, and the opening eccentric lever 74: is lifted to prize the carrier 32 loose, after which the counterweight will raise it to the position shown in Fig. 2. The trimming knives will be found to have trimmed the cones from the batter which is baked against the carrier or top baking iron 32 and to have keyed this baked batter to the carrier. Th operator then depresses tbepedal, catching it under a shoulder 9 thereby lifting and opening out the molds 22so that the cones can be lifted out. After this a knife is passed lengthwise what I claim as new between the rows of cores 35, to cut and part the bakedbatter keyed on thecarrier 32 and cause it to drop away. It is to be i noted that doing this none of this baked product will be caused to fall intothe molds or into cooked cones but will fall clear of the machine and to therear thereof, due to i the rearward overhang of the carrier, when in open position. 1 i i This invention is not intended to be restricted in scope to the specific embodiments shown, but contemplates such modifications as come within thespirit and scope of the claims. 1 a I m l v Having thus described my invention, and desire to secure by Letters Patent, is i V 1,-In a baking machine for cores. and the like, a frame, a mold comprisinga series of mold cavities and divided into sections lengthwise of said series, means to raise and lower said mold, cores forthe mold cavities, endguides on the frame and coactingelements on the moldisections disposed' and: adapted to separate and close the mold sectionsas they are raised and lowered, and a taper fac extending along the frame on each side of the mold and adapted to be engaged by the side mold sections as they ar lowered to co-operate with the end guides in'forci-ng said sections toflclose'd position. 1 1' 5 2.
